- Abstract:
- In the subjective evaluation of the NVH performance of a car model, it was found that after the suspension adjustment, the steering wheel vibration was still too large under the idle air conditioner condition, which affected the comfort of the whole car. Lab equipment was used to test the steering wheel vibration at idle speed, and the preliminary judgment was that the cooling fan fundamental frequency had a greater influence on the steering wheel shaking. Using the experimental modal analysis theory and method to analyze the excitation source, main transmission path and response point respectively, it was found that the cooling module (CRFM) and steering wheel modal parameters of the car were consistent with the cooling fan fundamental frequency. The test results show that the steering wheel shake can be significantly reduced by improving the structure of the damping pad and adjusting the cooling fan speed in combination with the actual situation of the vehicle.
